Stock substrates

LASEROPTIK stocks substrates for coatings in the wavelength range from 120 nm to 50 µm. Only the highest grade materials are used in the production of the components.

Nevertheless most optics are custom made at unique requirements and drawings. So please feel free to send your individual specifications.

All substrates are manufactured at high quality specifications in order to keep critical optical properties as scattering, absorption or beam deviation at a minimum. Besides flatness and roughness, the surface imperfections are another critical parameter.

Listed on the following pages LASEROPTIK stocks a selection of UV- and IR-transmitting substrates for fast delivery. A brief characterization of the substrates is given for every type.

Most orders of our customers can be met with FS-UV and FS-IR. For these we offer a large num­ber of plane and curved substrates.

In our standard sizes we can offer Fluorides as MgF₂ and CaF₂. For CaF₂ we offer four different qualities (VUV-grade for 157 nm, UV-grade for 193 nm or 248 nm and VIS-IR quality).

For applications with an absorption free range up to 4 µm, Sapphire or undoped YAG is recommended. Both materials are very hard and withstand temperatures up to 1.000 °C as well as high pressure.

ZnSe is a standard material for use from 500 nm up to 22 µm, because of its broad transmission range, its low absorption and scatter.
